The present invention provides a method and system for regulating network traffic levels. A second calculation device is also provided that calculates a flow velocity of air to flowing through a throttle valve in the engine, based on the pressure ratio equivalent value calculated by the first calculation device. The controller controls a first current to a first set of LEDs and a second current to a second set of LEDs. Alternatively, the at least one dielectric material portion may comprise a single dielectric portion of which the area has a sufficient lateral overlap with the area of the conductive via to insure that a liner-to-liner direct contact is formed within the range of allowed lithographic overlay variations. The functionality allows the node to convey its disconnection status to other communication participants.
